NVIDIA has confirmed that seven new monitors will be receiving the "G-Sync Compatible" badge come April 23rd. These FreeSync monitors have thus been certified by NVIDIA to work flawlessly with their implementation of VRR outside of the need of a dedicated, expensive G-Sync module. 

Three of these monitors are manufactured by Acer (KG271 Bbmiipx, XF240H Bmjdpr, and XF270H Bbmiiprx), one from LG (27GK750F (AUSUMPM / BKRUMPN)), one from ASUS (VG248QG), one from Gigabyte (Aorus AD27QD) and finally, one from AOPEN (27HC1R Pbidpx). If you are rocking any of these alongside an NVIDIA graphics card, you can enable VRR already, but for those who still haven't done so, know that your is one of the lucky few monitors to have NVIDIA's compatibility badge.
